Rana-de Arbol de Bosque Mesófilo

Cloud forest treefrogs in the genus Megastomatohyla (family Hylidae) are medium to large arboreal frogs native to the montane cloud forests of Mexico and Guatemala, inhabiting humid highland forests at elevations between 1,500 and 2,800 meters. These treefrogs have large adhesive toe pads, long limbs adapted for climbing, and typically green or brown coloration with cryptic patterns matching lichen-covered bark and leaves. They breed in temporary and permanent pools in forest clearings and at stream margins, with males calling from vegetation over water on rainy nights. Larvae develop in small forest pools. The genus Megastomatohyla was separated from the large genus Hyla based on molecular and morphological studies distinguishing Middle American cloud forest specialists from their lowland relatives. Several species in this genus have experienced significant population declines attributed to chytridiomycosis in combination with habitat loss, and some are now considered Critically Endangered or Endangered. The montane cloud forests of Mexico and Guatemala harbor exceptional amphibian diversity but face deforestation pressures from agricultural expansion, charcoal production, and illegal logging that continue to reduce amphibian habitat area.
